Parasite

In a cramped, damp semi-basement apartment lives a struggling family: father Gi Taek (Song Kang Ho), mother Choong Sook (Jang Hye Jin), son Ki Woo (Choi Woo Shik), and daughter Ki Jung (Park So Dam). One day, Ki Woo's friend, Min Hyuk, offers him a unique opportunity.

Min Hyuk suggests Ki Woo take over his job as a private tutor for a daughter from a wealthy family. Once Ki Woo starts, he cleverly gets Ki Jung hired to tutor the family's son, though they act as if they're strangers.

Their plan doesn't stop there. They devise a plan to get jobs for their parents in the same house. Gi Taek got a job as a driver, and Choong Sook as the maid, without the house owner realizing that they were a family.

At first, everything went smoothly, and they all enjoyed well-paid positions. However, a problem arises that causes them to lose everything. The movie highlights the rampant social gap where the rich flourish while the poor continue to struggle.
